I am still hoping I can buy your father lunch someday at the State Diner here in Ithaca and show him my coal stoker. I will not be burning any oil at all next winter and I will be removing the oil burner head and putting it in storage after I reinstall the burner tube cover plate on the dry side of the boiler. Is there any chance he might wander over to North Dakota to see CEGunthas one pipe steam system in his future hotel/Bed +Breakfast? I think that CEGuntha would really benefit from a visit and he will be able solve his problems with a walk through of his place with your father. It would be another great story for your dad to tell in his future book(s).
I keep hoping Mr. Guntha invests in an EFM DF520 coal stoker boiler to burn the local soft coal to make steam and hot water for the place as it will only cost him pennies per hour to heat it with the local soft coal that is mined in the nearby strip mines.
